← ScienceWhich outcome occurs when a metal-oxide-semiconductor field-effect transistor (MOSFET) gate voltage exceeds the dielectric breakdown limit?
A)Channel inversion layer formation ceases
B)Gate oxide breakdown and short circuit✓
C)Threshold voltage shifts to negative values
D)Substrate current increases linearly
💡 Explanation
When gate voltage exceeds the dielectric breakdown voltage, the gate oxide capacitance's insulating properties fail because the electric field exceeds the material's breakdown strength, immediately creating a short circuit. Therefore, gate oxide breakdown occurs, rather than other effects that require transistor operation within specified voltage range.
